PROBLEM TO BE SOLVED: To improve work efficiency of a welding operation and also to enhance welding quality in a welding equipment. SOLUTION: In a welding equipment 11, a supporting cylinder 21 is arranged on the outer periphery of the handrail pipe P1 along an axial center O2 parallel to the axial center O1 of the pipe P1 . The supporting cylinder 21 is held freely attachably and detachably on the handrail pipe P1 by means of a detachable mechanism 22. A welding torch 23, which performs welding for the handrail pipe P1 and the groove C of the core P2 , is made freely turnable along the outer circumferential surface of the handrail pipe P1 on the supporting cylinder 21 by means of a torch turning mechanism 24, and the position of the welding torch 23 is made adjustable by means of a torch position adjusting mechanism 25, enabling a copying movement along the outer circumferential surface of the groove C. |
